Many of the �spot removers� on offer today are nothing more than isopropyl alcohol with perfume. Using The base content in Nail varnish remover is typically acetone. Whilst it has some beneficial properties in cleaning china, removing sticky labels, covering scuffs on linoleum, etc, using it on your skin could actually exacerbate the spot, causing it to inflame.
The best way to dry a spot is to dip a clean cotton bud in isopropyl that has been poured into a glass and then dab the offending spot several times. Repeat the process approximately ten minutes later to help continue drying out the spot.
Happy spotting!
